7.Sand now filled the wells__________ water.( 。
A.insteadB.instead ofC.withD.in

分析 考查介詞,句意:沙子而不是水填滿了井.

解答 答案B,后面跟名詞water,首先排除A選項,instead是副詞,后面什么都不跟,如果填with,句意就是:沙子把水填到井里,很明顯,不通順.fill不和in搭配,instead of代替,根據句意"沙子而不是水填滿了井."選B.

點評 instead與instead of的區(qū)別:instead of是短語介詞,意思是"代替"、"而不是".它后面一般接名詞、代詞、動名詞或介詞短語作它的賓語.instead單獨使用時,與instead of不同,instead 是副詞,意思是"代替"、"頂替".

17.Would it surprise you to learn that,like animals,trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever imagined.
Although Charles Darwin thought that trees are competing for survival of the fittest,Simard shows just how wrong he was.In fact,theoppositeistrue:trees survive through their co-operation and support,passing around necessary nutrition"depending on who needs it".
Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks,making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy.This hidden system works in a very similar way to the networks of neurons (神經元) in our brains,and when one tree is destroyed,it affects all.
Simard talks about"mother trees",usually the largest and oldest plants on which all other trees depend.She explains how dying trees pass on the wealth to the next generation,transporting important minerals to young trees so they may continue to grow.When humans cut down"mother trees"with no awareness of these highly complex"tree societies"or the networks on which they feed,we are reducing the chances of survival for the entire forest.
"We didn't take any notice of it,"Simard says sadly."Dying trees move nutrition into the young trees before dying,but we never give them chance."If we could put across the message to the forestry industry,we could make a huge difference towards our environmental protection efforts for the future.

9.The underlined sentence"the opposite is true"in Paragraph 3probably means that treesC.
A.compete for survival
B.protect their own wealth
C.depend on each other
D.provide support for dying trees
10.The underlined word"it"in the last paragraph refers toD.
A.how young trees survive
B.how trees grow old
C.how forestry industry develops
D.how"tree societies"work
11.What would be the best title for the passage?C
A.Old Trees Communicate Like Humans
B.Young Trees Are in Need of Protection
C.Trees Are More Awesome Than You Think
D.Trees Contribute to Our Society.

15.It may seem strange that ice itself sometimes can protect crops from frost (霜凍)!Some growers actually spray their crops with water on a freezing night.Water freezes quickly on the plants and then a strange thing happens.As long as ice stays wet,it can't get colder than 0℃,a temperature many plants can stand.If the ice ever became entirely frozen and dry,it might drop many degrees lower,ruining (毀壞) the plants.But continually spraying water on the ice,the growers keep it from going below 0°C even if the air is much colder.This may be unbelievable but it saves the plants.
This strange kind of"ice blanket"works only on plants that are strong enough to stand the weight of frozen spray.The system is used even to protect banana plants on some Central American plantations.

36.As used in this passage,"ice blanket"meansC
A.a cold blanket       B.a spray of frost
C.a covering of ice    D.a warm blanket
37.This passage is intendedD.
A.to explain why some plants can withstand (耐) ice
B.to show how ice forms
C.to show that frost can be prevented
D.to give tips(竅門) on preserving (保護) crops
38.It can be concluded from the passage that ice would not protectC  from frost.
A.banana trees
B.pine trees
C.tender rose bushes
D.apple orchards (果園)
39.The best title would beB.
A.Frost Triumphs Again
B.Ice Can be Nice
C.Battle of the Farmer
D.The Helpless Plant.

19.Yesterday after school I took my boys through the drive way at McDonald's.It was a hot day and they wanted a nice cool treat.So I said yes.Plus the McSpiders are amazing for only $2!
So off we went.As I ordered I remembered a commitment I made to myself a year ago.
The commitment that every time I drive through the drive way I pay for the car behind me.I made this commitment because I go through the drive way about 4 times a year.So it's an easy one to keep.
As I drove around to pay the cashier the $6 for our order I really did not want to do this.I didn't want to pay or offer to pay for the car pulling up behind me.
In my head I begun to talk myself out of it."It's OK Nicole,you don't have to"."You haven't much money or work this week"."And what if it's a $40 order or more!"That's when the other voice stepped in.It said,"This is exactly the time you need to do it!When you don't"WANT"to.It's easy and good when your'in the mood',happy and full of cash.But love and kindness doesn't work that way.It isn't conditional and only given when it suits you!"
So I did it.I paid for the car behind.
I asked the cashier to add the car behinds order to my card.Which thankfully was only 2.95.Canyoubelieveit.2.95!!!
Anyway.That isn't the point.The point is that I did it.And doing it I completely made someone's day,and reminded them that there is love and kindness in this world.And to think…I almost didn't.I almost kept that $2.95 to myself!
